With the new Excaliber Spider Flyback Chronograph, Roger Dubuis once again demonstrates its technical prowess in the field of high-end chronographs. Inspired by motorsports, the 45mm manufacture chronograph is equipped with a carbon case and ceramic bezel. With skeletonized flanks, lugs, and rocker pushers, it adopts various features from this dynamic world.

The same applies to the five-arm rotor, which is designed like a rim. Under the hood ticks a fully integrated chronograph caliber with flyback function, which Roger Dubuis has braced against shocks, gravity and magnetism.
Innovations in Design
With this in mind, the RD780 automatic features several technical and aesthetic innovations, such as the chronograph clutch equipped with the “Second Braking System.” This mechanism adds stability to the stop-seconds hand, the display of the column-wheel mechanism on the dial side, and the balance at 9 o’clock, which is inclined at an angle of 12 degrees and, according to the manufacturer, has an inertia like a tourbillon, which enhances both precision and resistance.
Diamond-coated silicon elements in the escapement provide resistance to magnetic fields. Perhaps the most impressive feature, however, is the minute counter placed at 3 o’clock.
The patent-pending mechanism is equipped with a three-part hand bearing the digits 0, 1, and 2 and precisely runs along the numerals 0 to 9 on the right side to indicate the elapsed time. In addition, the RD780 offers a power autonomy of 72 hours.
